Abstract in brief

  • The study investigates how dopamine levels in the human brain's striatum relate to learning and decision-making, especially in relation to reward prediction errors (RPEs), which are the differences between expected and actual outcomes.
  • Using high-resolution monitoring of dopamine in Parkinson's patients during a decision-making task, researchers found that instead of solely encoding RPEs, dopamine fluctuations also incorporate "counterfactual" errors—how much better or worse the outcome could have been—suggesting a more complex role for dopamine in evaluating decisions.
  • This superposition of actual and hypothetical error signals may either reflect normal reward processing mechanisms or point to a diverse group of dopamine neurons that handle different aspects of learning, challenging previous models based mainly on animal studies.
